Scholars will be in their element with these decay equations found in a video that solves an example of alpha decay and beta decay. Gamma, or light, emission adds an extra concept to the equation. Then, through an analysis of which elements have changed, pupils realize they have just mastered transmutation.

Instructional Ideas

• Create additional practice problems for each type of decay

Classroom Considerations

• Requires prior knowledge of the periodic table
• Video best fits as an extra review of decay equations

Pros

• Talks through the thought process as each problem is solved
• Mentions a common mistake and how to avoid it

Cons

• None
